Application filed July 31, 1920. Serial No. 400,369.

To all whom t may concern.'

' p Be it known that I, ALBERT H. HEI'MBAGH,

a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain:

the invention consists of. certain novel features of construction and combination of parts, the essential elements of which are hereiiiaiter described with reference to the' drawlrigsvvhrch accompany and form a part of this specification.

In the drawings, Figure 1 is a front View of my improved incinerator; Figure 2 is a.l section taken on the line 2.2, `Figure 1;-

Figure 3 is a section taken on the line 33,

' the line 4 4, Figure 3'.

As shown in Figures 1 and 3, my incinerator consists of an incinerating chamber 1, enclosed by walls 2, and having@ the top thereof brought -in 'as .at 3 Ato the chimneyv is brought in on four sides,'as at 10Figure ses,

3, and a grate 11 is provided, partitioning the incineratingl chamber proper from the ash pit 12.

As shown in Figure 4, `the grate consists of twograte bars 13 and' 14, -journalled at. 15, 16 and 17, 18, respectively. lThe outer vends 19 and 20 of the grate bars are squared ofi' or otherwise suitably fashioned to receive thereon a lever 21, for shaking the ate. *i A suitable door 22 is provided to give` access to the incinerating chamber, and an ash door 23 gives access tothe ash pit below thegrates. ,.f In the constricted-portion of the incin- Verating chambera't 3, Figure 3, is a thimble 24 closed-by a grid924, and set ntothe'wal,

. Figure 2; and; Figure 4 is a section taken on therefore, im ortant.

and this thimble is used to connect a furnace 26 to the incinerating chamber by pipe'25.

The heater 27 is connected by the pipe 28 to the constricted portion'of the incinerating chamber at 29, and a pipe 30 leads from-the pipe 28 "to a point 31 where it enters the incinerating chamber below the grate.

Dampers 32 and 33 are provided forV controlling the draft through the pipes 28 and 30, respectively.. l

A grid 34, Figure 2, is set int'o the ma-` sonry near' the top ofthe chimney'7 to prevent burning material from passing out o the chimney.'

The grid .or screen 34 revents burning paper from iiying out of t e chimney whlle the grid 244 prevents paper or garbage,

dropped into the stack through the chute 8,

from getting l into and plugging up a thimble 24, and 4for .thisl reason, it will be noted thatthegrid 24 is 4at the inner end of'said 'thimble v above described and illustrated in the drawings, should `be particularly noted. starting a {ire-in the relatively smallvheater 27 damper 32,-willbe openedand damper i The importance 'of the arrangement of' pipes 28 and 30 and dampers 32 and 33,

in said heater 27, damper 32 will be closed .and damper 33 opened, so that then the hot gases' from said heater willjbe carrled into th'eincinerator` chamber at a point below the 'grate and -will-becausedto be passed upward, throughv the garbage and rapidly dr .the same'.

he above arrangement of smoke pipes 'and independently operating dampers The dimensions of the incinerating chaml is,

ber, constricted throat, and'grate area .are

proportioned to meet the' requirements of the capacity kof the building in which the incinerator is instal1ed.

While I have described my invention and.

illustrated it in several particularl designs, 1` dovnot wish it understood that l limit myself to this construction, asit is evident that the application of the invention Amay be varied in many ways within"the -scope of' thev following claim.

. The garbage on the grate of the incner! ator Will customarily contain a large amount of paper so that the commingled mass, when dry, may be ignited and will burn readily in the incinerator. It is, however, of the utmost importance that the garbage be thoroughly dry and this, as stated, is made possible by adjustment of the dampers 32 and 33 so as to cause the heat products of combustion from the small heater 27 to pass upward through the garbage on the grate of the incinerator. rl`he best garbage burning action will be produced when both the main heater 26 and the auxiliary or hot Water heater 27 are in action and the products of combustion from the latter are caused to pass upward through the garbage. Under these conditions the main heater will produce a very strong draft in the flue and the heat products of combustion from the auxiliary heater Will not only continue the drying action of the garbage but will insure a complete combustion of the garbage. rlFhe general arrangen'ient ofthe main and auxiliary heaters and the dampers in the branch pipes of the latter is highly important.

Claim:

The combination With a flue and an.in cinerating chamber at the base thereof, said incinerating chamber having a grate, of a main heaterhaving a smoke pipe connected to said flue above the grate of said incinerator., and an auxiliary heater having a smoke pipe with two branches, one branch being connected to said flue above the grate of the incinerator and the other branch thereof being connected to the incinerator chamber below the grate thereof, said two branch pipes having independently operative dampers for the purposes set forth.
